Answer:
180-43
Step-by-step explanation:
43 and x are supplementary which means they both should equal 180
For the first one I believe that the numbers are both odd and I am not sure about the second one sorry
2160 - 180 - 432 = 612
Each parallelogram is 3 square inches
divide by 3
612/3 = 264 parallelograms to complete the quilt.
